Seasonal effects on thermoregulatory abilities of the Wahlberg's epauletted fruit bat (Epomophorus wahlbergi) in KwaZulu-Natal, South Africa
Abstract Seasonal variations in ambient temperature ( T a ) require changes in thermoregulatory responses of endotherms. These responses vary according to several factors including taxon and energy… Expand
